Modification of 12-molybdophosphoric acid catalyst by blending with polysulfone and its catalytic activity for 2-propanol conversion reaction

Abstract

H3PMo12O40 embedded in a polysulfone film was prepared by blending H3PMo12O40 with polysulfone using dimethylformamide as a common solvent and its catalytic activity for 2-propanol conversion reaction was examined, The prepared film catalyst showed a higher yield for acetone but a lower yield for propylene than H3PMo12O40 itself. The decrease of acidic function of the film catalyst was mainly due to dimethylformamide strongly adsorbed on the acid sites of H3PMo12O40, while the increase of oxidation function was due to uniformly and finely distributed H3PMo12O40 in the film, When the film catalyst was used as a membrane, it showed higher ratio of acetone to propylene than H3PMo12O40 itself.
